Motivating paternal empathy and egalitarian attitudes to prevent maternal postpartum depressive symptoms: A randomized controlled trial.

In 30 seconds

This single-blind, parallel-group randomized controlled trial at a regional hospital in Japan tested a brief online intervention for fathers, delivered one month after birth, to promote empathy and egalitarian gender-role attitudes and prevent maternal postpartum depressive symptoms. The trial enrolled 262 fathers whose partners had full-term births and no psychiatric history. Maternal depression (EPDS ≥ 9) occurred in 4.5% of the intervention group and 9.3% of controls (adjusted odds ratio 0.45; 95% CI: 0.14-1.50). The intervention shifted fathers’ gender-role attitudes toward greater equality, but did not measurably change maternal symptoms, paternal empathy, or caregiving involvement.

Key findings

• Maternal depression (EPDS ≥ 9) was 4.5% with intervention and 9.3% with control (adjusted odds ratio 0.45; 95% CI: 0.14-1.50).
• Traditional gender-role attitudes decreased in the intervention group at 3 months (-1.74; 95% CI: -3.08 to -0.40) and 6 months (-1.52; 95% CI: -2.98 to -0.07).
• No significant differences were observed in mother-rated paternal empathy or fathers’ childcare and housework involvement.

Why it matters

The trial examines whether engaging fathers through a brief online intervention can influence maternal postpartum mental health. Although the intervention changed reported gender-role attitudes, it did not demonstrate measurable changes in maternal depressive symptoms or paternal caregiving behaviors. The findings distinguish an attitudinal effect from evidence of improved maternal outcomes and underscore the need for further evaluation.

What to keep in mind

The trial was conducted at one regional hospital in Japan and included couples with full-term births and no maternal psychiatric history, limiting generalizability. The confidence interval for the maternal depression estimate includes no effect.
